SNOVPLOW.

Application filed lflfarch` 3l, 1924. Serial No. 763,232.

This invention relates to machines for removing and clearing snow from railroads, street car lines and other roadways. In `fact this machine may be used for the clearing` of snow :troni any street, roadway or surtace from which it is desirable to remove the snow. t relates more specifically to that form of machine adapted to scoop up the snow by a forward extending' scoop and distribute'it to both sides of the machine or to either` side thereof as the operator may desire.

Another yobject of this invention is to provide a snow machine in which the front end of the scoop is pivotally connected to the scoopv proper and supported in. such a way that the scoopmay always be in operating contact with the surface :troni which the snow is to be removed, though the supports thereformay be elevated or depress-ed by any unevenness of the surface over which the scoop is operated.

It is another object and purpose ot this invention to provide a snow removing machine in which the parts are simple and by a person from one position.

Itis another object of this invention to provide a machine that embodiesits own motive power or that may be attached to the front part of some other machine having a suitable motive power, such as a truck, tractor or railroad locomotive. For the purpose of operating applicants device on track ways, the supportingwheels may be provided with langes for holding the machine on the track.

These and other advantages will appear from the description inconnect-ion with the drawings in which Figure 1, isa top plan view of the machine as a whole showing in dotted lines the propelling means.

Figure 15, is a ino-diiied form of snow scoop.

Figures 16 and 17 are detail views ot the runners on the front of the scoop blade.

In the figures or' the drawings similar reference characters are used 'to designate like parts of the machine.

The reference character A, is used to designate the machine as a whole. The machine is here shown as supported by four wheels, two rear traction wheels B and two .front wheels C, adapted to control the direction or motion of the machine and steered by a steering wheel 12 as in motor vehicles. Any suitable motive power may be used but in this instance we have represented diagrammatically a gasoline motor indicated by the reference character D but any'other suitable motive power may be used. The machine may be pushed by a tractor, truck or by a locomotive. In case some external motive lpower is used, the motive power represented by the character D may be dispensed with or permitted tov remain idle.

The form of motive power is no partv of this invention. The reference character 1 represents the frame suitably supported by the before described rear and front wheels. Upon the trame are located the housing or cab 23 the scoop 3 and the scoop controlling mechanism, the chutes et on each side of the cab and the operating mechanism for directing the course of the machine and for operating the snow removing parts. All parts of the mechanism are adapted to be .operated by an operator` situated within Cil the cab. On the front part ot' the machine and supported bj; the traine l is an inclined V shaped scoop having' its large part toward the fronttor scoopinp; up the snow. On the front end ot' the scoop, there is a pivotallv attached blade while on each side thereof, there is a snow wing' G. the snow wings are somewhz't 'formed in the shape of a roll, wide at the top and narrofr.v at the bottom. ttor guiding' the snow trom the tronty end oit the scoop to the revu' and upper end thereof and into the chutes Ll. In normal working conditions. as shown in Figure 3. the snow will be parted at the upper end of the scoop. party `going' to the. right side or chute and part to the le'l't side or chute of the machine. But it it should be desired to directv the snow into one chute, one ot theiwings will lie-rotated beyond the opening ot one chute and into line with the walls ot chute into which tbe snow is to be directed. The mechanism for rotating the wings is :specihealhv shown in Figure ll.

The scoop blade 5 with specitic oneratine' and hinge structure is speeilicallv shown in Figure To the central rear rart ot this blade, a lever S is suitablyy attached. Such attaching means as shown in the drawings ma;v be rivets. To the rear part ol lever S. is pivoted a wheel supporting' lever fl which is )ivotalliv supported hv stud l() attached to the scoop. The wheels which support the lever t) are mounted upon an axle ll which is securely tiXefl at its middle point to the end ot lever 9. Vthe wheels lil on the ends ot axle ll ma;Y be otI anv desired .torni or sir/ie. The wheels ,l2 through levers 9 and 8 act upon the scoop blade 5 to deflect itV when the scoop is passing' over roue'h or uneven surfaces. To control the motion olE the scoop blade 5, the 'following' specilif: hinge structure has been devised. ln Fit# ure two ot such hing are shown connected to the scoop blade and the scoop. These hinges are shown to be in two parts pi\- otall).Y connected together, one part l?) cureli.' attached to the scoop blade rivets l-l. the other part l5 slidabl)v connectel o the scoop by `auidesl. On the rear end ot the sliding); part oi.' the hinge a projeiition 1T haring' an opening' through which a longitudinal spring' ineinber 19 passes. The spring member 'lll is supported and carrier! bv nraclets 1S secureliv attached to the under side ot the scoop. It is pri-"terrible that the bracket 1S securely engage and hold the low gitudiual spring' l). but all 'these brackets except the end brackets. ma)rv be pern'iitted to ei'igagzje the sprine' to allow a slight longitudinal movement thereof when the springA is bent due to the .movement ot the scoop blad Te'nder norinal conditions. that is when thi scoop bladeV and scoop 4are in line... the longitudinal spring is straight, but shouldtie blade be moved up or down the spring will be bent either torward or backward due to the sliding' ot the part 'lo ol the hinge in the guide l. Figure i) shows how the spring bent when the scoop blade deflected up ward. The longitudinal spring' under nor-- mal conditions will maintain the scoop blade in line with the scoop and is sull'icientlv strong to elliect this purpose. liut should the blade come in contact with an)Y obstruction the spring' l?) will yie d so the blade will accommodate itsell to resisting obstruction. specific scoop structure, clearl)Y shor-:n l'fures 5 and has the advantage ot permittingv the scoop blade to propalw 'vs rljv clean the snrt'ace and more at a proper distance therefrom regardless ot the unerei;

nature oli the surface. Then the iront end ot the scoop passes over an elevation or bump in the surtace. either the runners 5 or the wheels lf2 will engage the uneven .surl'ace and bend the scoop blade 'ausintr it to rise over said surfaces. ll it were not for this specilic structure ol" scoop blade. permitting' the deflection Lhereot. the scoop niiie'ht become permanently injured b i.' contacting' with some rough or uneven surface. Thoue'l: this structure ot blade and blade connection permits the scoop to pass over obstructions without in iur)` thereto ret the specific torni ot hinges and spring' shown Iguarantee that the blade will always be held in working' relation to the surface and in scooping' condition due to the torce olE the spring' and the particular construction ol the hinges.

The. structure ot' the hinges and thi` springs 1for the snow wines are in all respects similar to that ot the sprintr and hinges 'for the snow blade.

Figure T shows the snow blade and the scoir in normal alined position while l"i 'I ure S shows the snow blade deflected up'a'arii aud the longitudinal spring bent. The ben: position ot the springt is shown in Figure il. rthe spring' lll as shown in Figures S' and i) pulls on the sliding part ot the hingeand tends to bring the blade back in line with the scoop.

For the purpose oi" operatineT the snow wings to direct the snow to both chutes or to the chute Von an)7 one side ot the machine the following mechanism is provided. Enf-h wine' has its own means ot operation and is.'

similar to the other one in ever v respect lland wheels 2li through gear mechanism f' operate longitudinal shafts 3l which bar ou the ends thereot arms The arms il are connected b v linls Ql to the snow wines (l. It will thus be seen that bv rotating' ihc hand wheels Q0. the snow wings may be ad justed at an;Y desired angle to the scoop.

For the purpose ol" elerating or loweringy the snow chutes. each chute isV provided wih a rack bar 2l which meshes with a pinion 25.

The pinions are operated by a hand wheel 26-through suitable gears 27 and shaft 28 on the ends ot which the pinions 25 are located. rihe` chutes 4 are connected to thc :trame by hinge mea-ns 7 shown in Figure 12.

VThe hinges 7 through the above descril d adjusting means permit the chutes to be elevated or lowered at such angle as the opera tor desires.

On the youter end ot each chute a oldable snow deiiector 29 is provided. rIhis detlect'or is composedk of sections which in folded position overlie each other as is clearly shown in Figures 3 and 4. The deliector in open position is shown in Figure 13. Any suitable rmeans may .be used for connecting the sections or" the detlector. In the present illustration, there is shown a strap 29. The sections of the deiiector are pivoted to each other and to the chute as is clearly shown in ,Figures 13 and 14. For operating the de- .iectors, open and close the sections, a system of levers and links is provided. as shown in Figure 13. A. hand lever 30 is pivoted to the chute 4 and has pivotedly connected thereto linl31 Which operates link 32 pivotedly mounted upon the chute 4. Attached to the end ot link 32 opposite to the attachment of link 31, is a second link 33 extending fromV linlr`32 to an arm 34 extending from the outer section of the detiector.

vFigure 15 shows a modified Jform of scoop in which the scoop blade and the snow Wings are attachedtothe scoop proper by ordinary hinges.
